Micro-pollutant removal product picks up Aquatech Innovation Award

Envirotec Magazine

This allows it to remove a wide range of organic micro-pollutants, using lower energy and resource consumption when compared to reference technologies, resulting in low CO2 footprint and operational expenses, according to Aquatech. Then a little bit of ozone is added to avoid the formation of bromates.

Reappraising assumptions about ozone in European cities

Envirotec Magazine

Ozone levels near the surface in urban environments are lower than expected, in the results of an Austrian research group The 40-meter-high monitoring tower of the Innsbruck Atmospheric Observatory near the centre of the city of Innsbruck continuously provides data on the composition of the atmosphere at ground level.

Experts to help tackle air pollution from domestic solid fuel burning in Greater Manchester

Envirotec Magazine

Ricardo already advises the ten Greater Manchester local authorities and runs their reference air quality monitoring network. and PM10), nitrogen dioxide (NO 2) nitrogen oxide (NO), carbon monoxide (CO) and ozone (O 3). The devices will monitor particulate matter (PM 2.5 Ten of the 43 devices will also monitor carbon dioxide (CO 2).

AI-based project provides accurate, real-time, hyper-local air quality data, says group behind it

Envirotec Magazine

To perform this, the sensors were co-located with those at high-precision reference air quality station Weybourne Atmospheric Observatory (right) on the North Norfolk coast. Kingston University investigated how the presence of other gases and environmental conditions affects the accuracy of these air sensors.

Lockdown impacts: New study collects data on pollutants in the atmosphere

Envirotec Magazine

It focuses on the following air pollutants: nitrogen dioxide, particulate matter, ozone, ammonia, sulfur dioxide, black carbon, volatile organic compounds (VOCs), and carbon monoxide. In contrast, ozone levels increased. This increase was a result of atmospheric chemical processes caused by reduced nitrogen oxide levels in the air.

Measuring NOx in combustion

Envirotec Magazine

Reference method: chemiluminescence (CLD). The European Standard EN 14792 specifies chemiluminescence as the standard reference method (SRM) for the measurement of NOx in stationary source emissions. What follows is a run-down of the key considerations that underpin the design of a true reference analyser. Ozonator design.

Publicly accessible, hyper-local air quality sensor network launches in Camden

Envirotec Magazine

The new network also refreshes 60x more regularly than the existing system of air quality reference stations in Camden, “capturing and reporting hyper-local air quality data every minute to map the issue in real time” Initial data from beta testing over the past month has already revealed a number of interesting findings, says AirScape.
